As of early 1990s, it was present in American [4] and European [5] gasoline in small amounts, and by 2011 its share in US gas varied between 2 and 8%. [6] Using a quantitative structure-activity relationship (QSAR) prediction model, 2-Methylpentane has a research octane number (RON) of 75, motor octane number (MON) of 77, and cetane number (CN ...
It is of similar structure to the isomeric 2-methylpentane, which has the methyl group located on the second carbon of the pentane chain. As of early 1990s, it was present in American [3] and European [4] gasoline in small amounts, and by 2011 its share in US gas varied between 1.5 and 6% [5] It has close research and motor octane numbers of 74 ...

3-Ethylpentane (C 7 H 16) is a branched saturated hydrocarbon. It is an alkane, and one of the many structural isomers of heptane, consisting of a five carbon chain with a two carbon branch at the middle carbon. An example of an alcohol derived from 3-ethylpentane is the tertiary alcohol 3-ethylpentan-3-ol. [3]
The structure of 3-methylpentane is viewed as consisting of two parts. ... then the name would be 3-ethyl-2,3-dimethylpentane. When there are different alkyl groups ...
3) 2 (C 2 H 5). Isopentane is a volatile and flammable liquid. It is one of three structural isomers with the molecular formula C 5 H 12, the others being pentane (n-pentane) and neopentane (2,2-dimethylpropane). Isopentane is commonly used in conjunction with liquid nitrogen to achieve a liquid bath temperature of −160 °C.
The optical center is the middle carbon of the pentane backbone, which is connected to one hydrogen atom, one methyl group, one ethyl group – C 2 H 5, and one isopropyl group – CH(CH 3) 2. The two enantiomers are denoted (3R)-2,3-dimethylpentane and (3S)-2,3-dimethylpentane (the other simplest chiral alkane is its structural isomer 3 ...
